Sandwich is a town in Carroll County, New Hampshire, United States.

Chartered in 1763 by colonial Governor Benning Wentworth, the land was considered so inaccessible that the grant was enlarged, making Sandwich one of the largest towns in the state.

At that time the town contained farms, stores, mills, churches, schools, carpenters, blacksmiths, and wheelwrights.

By the end of the 1800s much of the population had left Sandwich to live in cities to the west.

Sandwich began to be an attraction for visitors, summer residents and artists, which continues to this day.

Mount Israel, elevation 2,630 feet (802 m) above sea level, is within the national forest close to the geographic center of the town.

27.4% of all households were made up of individuals, and 13.9% were someone living alone who was 65 years of age or older.

Male full-time workers had a median income of $57,917 versus $40,804 for females.
